Woww.. you all guys are really very lucky as you have a car. I dont have even a bike. I am working hard these holidays for getting atleast a bike
right now just my own 2 feet and a skateboard but I have been looking into the hot water system of modifying your engines system to run on a combination of hot water and gas so once I get back to a place that I need a car I will look into it
My car runs on regular @ss fuel. Luckily it gets really good gas mileage... somewhere around 40 mpg which is great as it's not even a hybrid.
